Filed: 1922-12-05
Abstract: 205,387. Lewin, J. N. Dec. 5, 1922. Cases. - A combined table and gramophone cabinet comprises a deep box-like receptacle divided by a transverse partition 6 into two compartments for the gramophone and records respectively, and a lid 3, which forms the table top, mounted on a vertical pivot 15 so that it can be swung aside to give access to the gramophone while still covering the record receptacle. The motor board 13, carrying the turntable 12 and motor 14, is hinged to the board 11 carrying the tone-arm and can be turned up to give access to the motor. The horn 5 is preferably of thin wood. The gramophone may be rotatably mounted. the receptacle then being provided with doors or louvres on its three sides so that the direction of the sound may be varied without moving the table.

Title: Self-cleaning ash tray
IPC: A24F19/00
Filed: 1962-08-30
Abstract: 996,582. Ashtrays. A. M. McKENZIE. Aug. 30, 1962 [Sept. 5, 1961], No. 33259/62 Heading A2M. A self-cleaning ashtray comprises a casing 1 having a top opening 11, a plate 34 slidably mounted for reciprocatory movement beneath the opening, a wiper blade 26 engaging the top surface of the plate and a motor 47 for reciprocating the plate. The casing 1 comprises a bottom 2, side walls 3, rear wall 4 and a front wall 5, the latter being connected to an ash receptacle 9. A metal frame 15 is mounted inside the casing 1 for pivotal movement about trunnions 16 against the action of a spring 18. The motor 47 is mounted on a bracket 42 fixed to the frame 15 and drives, through gearing 50, a shaft 43 to the end of which is connected a crank 44 having a pin 45 which engages in a slot 38 in the plate 34. Also fixed to frame 15 is an arm 23 to which the wiper blade 26 is attached. The sides 20 of frame 15 are connected by a partition 21 to which is fixed a timer 57. The timer includes a cylinder 58 and a piston 59 having a rod 60. The rod 60 has an annular groove 62 at its end which projects through the head 61 of the cylinder. The piston is urged outwardly by a spring 63 and is normally held in retracted position by a latch 70 which engages the groove 62. The latch 70 has a leg 71 which is fixed to the bottom 2 of the casing 1. When a cigarette butt is pressed on the plate 34 the frame 15 pivots about the trunnions 16 so that the latch 70 is released and the rod 60 moves outwardly under the action of spring 63. When the piston 59 contacts the stud 74 an electric circuit is made from earth through the piston 59 and stud 74 to the motor 47, from the motor 47 to batteries 54 and back to earth. The motor is then energized and causes shaft 43 to rotate so that crank 44 causes the plate 34 to reciprocate. Towards the end of its rearward travel the edge of plate 34 presses back the end portion 29 of a plunger 28 which is mounted beneath the arm 23. The portion 29 is thus brought into the path of the pin 45 on the crank 44 which releases it from the edge of the plate 34, so that the plunger 28 shoots forward and strikes the blade 26 to clear it of ash. As the shaft 43 rotates a cam 67 thereon returns the piston 59 to its retracted latched position while a second cam 80 on the shaft completes a holding circuit for the motor 47 via contacts 76, 77 until the completion of the cycle. Alternatively, the reciprocation of plate 34 may be initiated by a manually operable switch.

Abstract: 487,152. Eyelet - setting machines. BIFURCATED & TUBULAR RIVET CO., Ltd., and PATERSON, L. M. Dec. 11, 1936, No. 34050. [Class 43] [Also in Group XXII] A setting-machine for hollowended rivets has centring means on the anvil for positioning the drilled components to be riveted relatively to the plunger, and the plunger and anvil are so constructed that upon operation of the plunger the rivet head is pressed down flush with the upper surface of the components which are formed into a countersink, and the lower edges of the components are caused to protrude below their lower surface. A rivet 21, Fig. 5, having a short recess 21a drilled therein is delivered from a shoot 25 to a split holder 20 the parts of which are carried on leaf springs 23. The rivet feed may be similar to that described in Specification 294,754, [Class 89 (iii)]. The sheets A, B to be riveted are located by a spring-pressed pin 27 which enters the drilled hole therein, and are clamped by a pad 11b. The rivet head is forced into the work, so that it forms a countersink and its head is flattened, by a tool 6. A recess 26a, 28a in the lower anvil parts 26, 28 produces a joint wherein the edges A<1>, B<1> of the plates are caused to protrude below the lower surface of the plate B, the movement of the pin 27 being restrained in the last stage of the setting operation. The slide 7 carrying the plunger 6 is driven from a crank 8, the relative position of the tool being adjustable by a wedge 29.
